I'm not sure I understand what you mean with "a wrapper of standards like ADBC and ODBC".
Do you mean it would use ADBC/ODBC for implementation of the connector, but still expose its API as Rust traits? Or do you mean it would replace its API with ADBC and remain using Rust implementation of database clients? In this scenario, the C ABI of this library could be used from other languages, as you describe. --- > This also reduces the chances of you providing things that are heavily biased > towards the way the databases you supported initially work. Oh yes - that I have found to be the case when implementing connectors. It is hard to be unbiased, since you don't know the full extent of all of the features of different database client you will eventually support. --- I've tried looking at the ADBC defines for Rust, but I can only find a draft of the API. Are there any implementations of ADBC in Rust I could use for reference?
